The Alaska Bore Tide: What, When, Where, Why & Who?


The Turnagain Arm bore tide is basically a wave formed when a super low tide and a super high tide crash into each other in the narrow and shallow Turnagain Arm. The wave can come twice a day and is often surfed by local riders, who are sometimes able to surf a very long time on 5-10 foot faces.

It occurs 2-3 hours after the low tide time in Anchorage, Alaska. It is total luck (and anyone is so lucky!) on any given day to see the bore tide, as shifting, silty mud, icebergs and rivers of Turnagain Arm make for an ever-changing and unpredictable creature. Usually, a minus low tide and a high tide about 27 feet are required to make a wave big enough to surf.

Bore Tide is best viewed on the Seward Highway at the 4th or 5th turnout towards Anchorage. However, it can be viewed at all 5 turnouts with about an hour difference from the 5th to the 1st spot.
